Your TV looks worse than the one in the store because of a single setting

So, you bought a new TV. It looked great in the store, and you were excited to get it set up in your living room in time for the big game or to binge-watch that hot new streaming show. But it doesn’t look as good as it did in the store, and you’re disappointed. Before you angrily call the shop to complain or repackage the TV to send it back, there’s a single setting you probably need to tweak to improve the picture. In fact, you might need to adjust a few settings.
